The new rope coring hydraulic hammer drill was successfully developed.

The New Technology 2 Room of the Institute of Exploration Technology makes full use of the achievements and advantages in the research and development of hydraulic DTH hammer technology, aiming at the development situation of resource exploration, and successfully developed a new generation of SYZX series rope coring liquid hammers. Provided a new machine for the geological resources survey and the vast market for the rapid development of rope core drilling.

The technology combines the advantages of rope coring and hydraulic impact rotary drilling, making full use of the rope coring without the need to raise the drill every time, the auxiliary time is small, the hydraulic dive hammer drilling efficiency is high, the core blockage probability Less, increase the superiority of the return stroke, especially in the fractured formation and hard and compact slipping formation, can double the drilling efficiency and reduce the overall cost.

Compared with traditional drilling tools, this series of rope-pulling hydraulic hammers has the following characteristics:

*The built-in hydraulic DTH hammer adopts the YZX hydraulic hammer structure which has obtained the invention patent and has been drilled into the test by the 5000m depth of 5000 well. Therefore, it has better advantages in adapting to the depth of the well, the stability of the work, the life of the wearing parts, and the like;

*The hydraulic hammer adopts the double nozzle distribution structure and moves with the difference of the area of ​​the hammer valve. Reducing the number of seal pairs simplifies the structure of the drill;

* There are no fragile spring parts in the hydraulic hammer, and the drill has a long service life;

*The hydraulic hammer cancels the fixed throttle ring, and the impact of the anvil pad is small, which is beneficial to deep hole drilling;

*The seals between the inner and outer tubes and the high and low pressure areas of the valve hammer are made of metal mechanical seals, which have high wear resistance and long service life;

*The device for transmitting impact energy adopts a structure with mutual tolerance and rigidity, which is simple, reliable and long in life, and easy to replace;

* The outer tube transmits torque and impact work structure is simplified and increases the safety strength.

The machine is compatible with conventional rope core drilling tools and can be applied to the exploration of various metal ores, including: gold, lead-zinc, and iron ore, copper, etc.; various rock layers include: metamorphic rocks, igneous rocks and sedimentary rocks Various veins, faults and fracture zones; complex formations that are prone to collapse and easy to block cores; also suitable for rivers, lakes and oceans and scientific drilling.
